HI @CaptainBeardsEyesBeard 👋 ,

I strongly guess you missed to add the port also to the DriverParams option like so in your case:

_WD_Option('DriverParams', '--port=9515 --log-path="H:\AutoIT Scripts\AutomationTest\Framework\chrome.log')

Also next time please show your capabilities string (or json) for a better analysis, thanks 🤝 .

Best regards

My setup chrome function is which includes the port no? 

_WD_Option('Driver', 'H:\Quality Assurance\WebDriverUDF\chromedriver.exe')

_WD_Option('Port', 9515)
_WD_Option('DriverParams', '--log-path="' & @ScriptDir & '\chrome.log"')

$sDesiredCapabilities = '{"capabilities": {"alwaysMatch": {"goog:chromeOptions": {"w3c": true }}}}'

You need the port at two places:

_WD_Option('Port', <PORT>)
_WD_Option('DriverParams', --port=<PORT> ...)

See my post above. Simple replace ...

_WD_Option('DriverParams', '--log-path="' & @ScriptDir & '\chrome.log"')

by this ...

_WD_Option('DriverParams', '--port=9515 --log-path="' & @ScriptDir & '\chrome.log"')

... and it should work. Otherwise there are more issues, but I don't think so 😀 .

Please tell me why I need to specify the port twice?

_WD_Option('Port', '9515')
_WD_Option('DriverParams', '--port=9515 --log-path="' & @ScriptDir & '\chrome.log"')

sorry my English!

Hi @SEKOMD 👋 ,

chomium based browsers like Chrome or MSEdge are try to use a random port on opening (since ~Aug 2024).
Googles explanation why they changed the behavior can be found here.

1. You simply need the port in DriverParams to override the intended behavior to randomly find a available server port, by supplying the desired port number as a parameter.

   The _WD_Option('Port', 9515) line lets the webdriver UDF know the port number to use to communicate with the webdriver console [...]

I guess this should be explanation enough, right 😀 ?
